6 curated breaking changes across major versions of rlang. Use this as a migration checklist before bumping dependencies.
`abort()` now displays errors as fully bulleted lists. Error headers are displayed with a `!` prefix. See <https://rlang.r-lib.org/reference/topic-condition-customisation.html> to customise the display of error messages.
`abort()` now displays a full chain of messages when errors are chained with the `parent` argument. Following this change, you should update dplyr to version 1.0.8 to get proper error messages.
`abort()` now displays function calls in which a message originated by default. We have refrained from showing these calls until now to avoid confusing messages when an error is thrown from a helper function that isn't relevant to users. To help with these cases, `abort()` now takes a `call` argument that you can set to `caller_env()` or `parent.frame()` when used in a helper function. The function call corresponding to this environment is retrieved and stored in the condition.
cli formatting is now supported. Use `cli::cli_abort()` to get advanced formatting of error messages, including indented bulleted lists. See <https://rlang.r-lib.org/reference/topic-condition-formatting.html>.
New `try_fetch()` function for error handling. We recommend to use it for chaining errors. It mostly works like `tryCatch()` with a few important differences.
Dropped support for the R 3.2 series.
